Original application led July 2, 1918,

To all whom t may concern:

Be it known that I, IVILHELM Rasen, a citizen of the Swiss Republic, and resident of Binningen, near Basel, Switzerland, have invented new and useful Improvements in Apparatus for Dyeing, Bleaching, or like Treatment of Cops', of which the following is a full, clear, and exact specification.

Tn dyeing, bleaching or like treatment of cops by means of a circulating liquid it is known practice to mount the cops on metal or rubber spindles and so to pack them that the channels produced by this mounting are stopped up by filling material so that there may be uniform dyeing or bleaching of the textile material` It is also known practice in dyeingV cops without spindles to press them closely together. Hitherto the preliminary pressed cops have been packed on the perforated bottom of the container in such a way that the circulating liquid must pass through the packed cops in a direction at right angles to their longitudinal axes. Or the packing and pressing of the cops has been performed in the container upon the perforated bottom and the container has been so placed that the liquid must pass through the cops in the longitudinal direction.

The present invention relates to the packing and treatment of the cops in the lastnamed manner. In the known procedure, whether in consequence of insuflicient pressure or in consequence of incorrect application of the cops to the perforated walls of the container', an irregular treatment of the cops in the pack is to be expected. In the apparatus according to this invention a thoroughly uniform treatment of the pack is obtained in a container by packing and pressing together the cops on their paper tubes in layers in the container, their treatment with the liquid being in the longitudinal direction between perforated ends of the container and for insuring the position of the outside cops in the container there is inserted in the end of the paper tube of the cops a short stopper before the packing operation. This stopper forms a retainer for the yarn and a protection for the endY Specicatou of Letters Patent.

ditional packing, and prevents the formation of empty spaces or dead corners which give rise to irregular passage of the liquid. There is thus obtained throughout the whole a tightly closed packing and even at the extreme ends of the cops a thoroughly.

tion of the packing on an enlarged scale and Fig. 3 is an end elevation thereof.

The pack container a is packed with cops to be treated, outside theapparatus in which the treatment is to occur. For this purpose the container is placed upon a support, resting on the unperforated side wall which is to the right hand in Fig. l and the cops are laid in it in the horizontal position in layers and pressed transversely to their longitudinal axes, so that they finally form a packing in which all passages between the several cops as well as the longitudinal openings of their paper tubes are tightly closed. A part of this packing is shown in Figs. 2 and 3 drawn to an enlarged scale, from which the mode of laying and pressing together the cops b will be apparent. Before the packing those cops which are to abut against the perforated end walls c and 'CZ or". the container are provided with small short Stoppers e which are stuck into the openings of the cop tubes in order to serve as a retainer for the yarn and as a protection for the end of the paper tube as well as to close the opening. These stoppers also serve for insuring the position of the cops in the container during the centrifuging of the pack. When the cops have been packed into the container a the latter, turned through an angle of 900, is inserted into the tween two filter chambers g, it, Fig. l, andy the cover z' of the upper filter chamber (7,

the walls of which are arranged against the container a itself, is firmly pressed down 0 the fibrous material throughout.

so as to render tight thc side packing` of the filter chambers. The necessary pressure on the cover 'z' may be exerted for example by means of the cover and screw bolt 761.

The closed Vat f which is, provided with the usual accessories, such as a pressure gage, safety valve and the like, is fed at m with the liquid under pressure. The liquid is driven from above downward through the stationary cops in the longitudinal direction of the latter and through the filter' chambers g, )'L and leaves the vat f at a. The perforated end walls 0, cl of the container distribute the liquid uniformly over the pack and the uniform tight compression of the cops, by means of which all intermediate passages and all dead spaces in the pack for the direct passage of the liquid are closed, insures a uniform saturation of lhen the treatment is complete, the container a with the goods in it is removed from the vat f and as may be necessary is passed to a centrifugal machine for the purpose of centrifuging the goods.

ills shown in Fig. l, the apparatus comprises two filters g, it for the purpose of filtering t-he treating liquid which often may contain impurities or undissolvcd parts. With these two filters the apparatus is capable of being used for the treatment of the goods on the known principle of alternateters serves for filtering purposes when the liquid flows in one direction, while the other serves for that purpose when the flow of liquid is reversed.

This application is a division of my coponding application Serial No. 243,072, filed July 2, 1918, now Patent 1,317,220, Sept. so, 1919. Y

What I claim is:

An apparatus for dyeing, bleaching and the like of cops by means of a circulating liquid, comprising a container having two opposite perforated walls, its`other walls being unperforated, arranged for packing in the cops under pressure upon an unperforated side wall and perpendicularly to said perforated walls of the container, two transverse filter chambers ar anged to reoeive said container with ,its perforated walls between them and liquid circulating means connected to said filter chambers so as to cause a flow of liquid through the same and the packing of the container in the longitudinal direction of the cop, substantially as and for the purpose described.

In witness whereof I have hereunto signed my name this 25th day of March, 1919, in the presence of two subscribing witnesses..
